Philips, the worldwide leader in automated external defibrillators (AEDs), designed the HeartStart OnSite Defibrillator for the ordinary person in the extraordinary moment. The first and only AED available without a prescription, the OnSite is designed to be the easiest to setup and use and the most reliable defibrillator available.
Philips innovative technology, based on extensive research and user feedback, has produced a defibrillator so easy to use that you can potentially save the life of a co-worker, friend, or anyone else stricken with sudden cardiac arrest

Easy To Setup

The Philips HeartStart OnSite Ready-Pack configuration is virtually ready to rescue out of the box. Enjoy peace of mind knowing your device is deployed correctly and is ready when needed:

  • Arrives with pads cartridge and battery already installed
  • Device positioned inside carry case with optional spare pads cartridge in place
  • Just pull the green tab to launch the initial self-test
  • Automatic daily self-tests, including pads, help ensure continued readiness

Easy to use

Using the HeartStart OnSite Defibrillator is simple. Pulling the green handle activates the defibrillator and its voice instructions and visual icons. These instructions are paced to your actions, to help guide you through the entire process – from placing each pad on the patient to delivering a defibrillation shock and performing CPR.


Clean design and clear voice instructions, including CPR coaching, are designed to help instill the confidence that’s needed when treating a person in cardiac arrest.


The first Biphasic therapy with sufficient evidence to be classed “standard of care” and “intervention of choice” by the American Heart Association, SMART Biphasic effectiveness is backed by over 40 published, peer-reviewed studies. And with patented Quick Shock, the OnSite is among the fastest in class at delivering a shock after CPR. Studies show that minimizing time to shock after CPR may improve survival.  “Reduction in the interval from compression to shock delivery by even a few seconds can increase the probability of shock success.”
